Doesnt everyone do the swapping gender mix with some characters? the ones you say are mostly gender switching as weelll. Just the Gaara/Rock lee would be horrific ones. Though The one who plays Rock Lee would be a bit different than the official anime/manga self.

Woah! I just thought of something. Theres this popular dance in Korea thats becoming popular around the world. It's done by a Girl band called wondergirls. You can probably have your group do the dance.
